Abstract
A detent method for a medical imaging system. The method comprises obtaining a braking function F(S, V) between a distance S moved by a moveable component of the medical imaging system when a brake is applied to the component and a velocity V of the component and obtaining a measured velocity Vm of the component before the brake is applied. A braking position PB is determined based on a target position PT, the measured velocity Vm and the braking function F(S, V), wherein the brake is configured to be actuated when the component reaches the braking position PB.
Claims14
A computer-implemented method for a medical imaging system, the method comprising:
- obtaining a braking function between a distance moved by a moveable component of the medical imaging system when a brake is applied to the component and a velocity V of the component;
- obtaining a measured velocity of the component before the brake is applied;
- and
- determining a braking position based on a target position, the measured velocity and the braking function, wherein the brake is configured to be actuated when the component reaches the braking position;
- obtaining a measured position of the component after the component stops moving;
- and
- if a braking function re-calibration rule is triggered, adjusting the braking function based on:
- a distance between the braking position and the measured position;
- and
- the measured velocity, wherein the braking function re-calibration rule includes that the measured position does not fall within a detent window relative to the target position.
A system for performing a detent method for a medical imaging system, the system comprising:
- a memory that stores a plurality of instructions;
- and
- a processor coupled to the memory and configured to execute the plurality of instructions to:
- obtain a braking function between a distance moved by a moveable component of the medical imaging system when a brake is applied to the component and a velocity of the component;
- obtain a measured velocity of the component before the brake is applied;
- and
- determine a braking position based on a target position, the measured velocity and the braking function, wherein the brake is configured to be actuated when the component reaches the braking position;
- obtain a measured position of the component after the component stops moving;
- and
- if a braking function re-calibration rule is triggered, adjust the braking function based on:
- a distance between the braking position and the measured position;
- and
- the measured velocity;
- wherein the braking function re-calibration rule includes that the measured position does not fall within a detent window relative to the target position.
